Research on High Performance Vitrified Bond Diamond Wheel


Article Preview

Two kinds of vitrified bonds, bond L (low temperature bond) and bond G (high strength bond), were blended by ball-milling in producing diamond wheels. Proper Sintering techniques were employed by analyzing properties of the wheel through DSC testing and fracture strength. The wheels were applied in machining PDC in comparison with similar product on market. It showed that the blended bond reached its highest fracture strength when bond L amount was about 20wt~24wt%; combination of this two kinds of vitrified bonds would improve the wheel’s comprehensive properties by raising its fracture strength to 89MPa when bond L takes up 22wt%; service life of wheels prepared by this blended bond was 30~50% longer than similar market product and efficiency improved by more than 20%.
